Answer:
The answer to your question is 3.75 mg
Explanation:
Data
Radium-223
half-life = 11 days
mass = 60 mg
total time = 44 days
Process
1.- Draw a chart to start the calculation
Mass Number of days Half-lives
60 mg 0 0
30 mg 11 1
15 mg 11 2
7.5 mg 11 3
3.75 mg 11 4
Total number of days 44
Mass active after 44 days = 3.75 mg
I think plant cell because they have cell wall that protect them.
The amount of sodium bromide that would be formed from the reaction will be 7.5524 grams
<h3>Stoichiometric calculation</h3>
Looking at the equation of the reaction:
The mole ratio of CuBr2 and NaCl is 1:2.
Mole of 16.4 grams of CuBr2 = 16.4/223.37
= 0.0734 moles
Mole of 22.7 grams of NaCl = 22.7/58.44
= 0.3884 moles
Equivalent mole of NaCl = 0.1468 moles
Thus, NaCl is in excess while CuBr2 is limiting.
Mole ratio of CuBr2 and NaBr = 1:1
Mass of 0.0734 mole NaBr = 0.0734 x 102.894
= 7.5524 grams
